The plurality of light illumination elements 111 is arranged along the peripheral edge portion 1211 of the base wall 121 to form a ring-shaped illumination unit. As shown in FIG. 4 of the drawings, the plurality of light illumination elements 111 of this preferred embodiment form four illumination sections to provide a rectangular ring-shaped illumination unit.

The circuit board 112 can be a rigid printed circuit board, Or it is preferred that the circuit board 112 is embodied as a flexible circuit board that can be easy to bend, so that the circuit board 112 can be bent at corners of the support base 12 in the cavity 123 for guiding the light illumination elements 111 to extend along the peripheral edge portion 1211 of the base wall 121, and also the light illumination elements 111 are ensured to be provided to face towards the opening 124 after bending the circuit board.

The circuit board 112 is attached to the base wall 121 by any suitable mounting manner such as by fixing screws. In this preferred embodiment, the circuit board 112 of the light source 11 is attached to the base wall 121 by a bonding glue.

It is appreciated that the person of ordinary skilled in the art should understand that the positions of the plurality of light illumination elements 111 are aligned with edge portions of the a plurality of light shading elements 30, so that most of the light beams emitted from the plurality of light illumination elements 111 are projected to the a plurality of light shading elements 30.

According to this preferred embodiment, the shadow artwork platform comprises the plurality of the control spacers 20 for detachably mounting the plurality of the light shading elements 30 in front of the plurality of light illumination elements 111, so as to create an illusion of depth for the shadow artwork 100.

Each of the plurality of light shading elements 30 of this preferred embodiment may comprise an opaque artwork area 31. The opaque artwork area 31 can be made of any suitable opaque material such as paper, plastic, or painting material. As an example, each of the plurality of light shading elements 30 can be made by papercuts from a paper to define the opaque artwork area 31 having a plurality of penetrating openings 32. The light beams from the light source 11 cast on the opaque artwork areas 31 to form shadows while the light beams projecting towards the penetrating openings 32 are allowed to pass therethrough to provide illumination to an outer side of the shadow artwork 100.

Accordingly, a plurality of artwork papers can be provided to a user, and the user is able to prepare his or her desired pattern of each light shading element 31 by configuring a shape of the opaque artwork area 31 as well as to obtain a desired shadow artwork pattern by the combination of the plurality of light shading elements 30 which is made by the user and is overlappedly and spacedly arranged in front of the plurality of light illumination elements 111 for creating the desired shadow artwork pattern when the plurality of light illumination elements 111 is turned on to cast light on the opaque artwork areas 32 of the plurality of light shading elements 30.

Alternatively, the plurality of light shading elements 30 also can be prepared by the shadow artwork platform. In other words, the user also may not need to make his or her desired pattern of each light shading element 31 by paper-cuts, each of the plurality of light shading elements 30 has a predetermined pattern, and the plurality of light shading elements 30 is arranged to provide various artwork patterns for the user to select therefrom and arrange his or her desired combination from a selected group of light shading elements 30.

Alternatively, as shown in FIG. 3A, one or more light shading elements 301 of the light shading elements 30 may comprise a transparent sheet 33 which is made of transparent glass or plastic, and an opaque artwork area 31 which is formed by painting a painting material on a partial area of the transparent sheet by the user or by the provider of the shadow artwork platform.

A bottom light shading element 301 is embodied to comprise a transparent sheet 33 having an opaque artwork areas 31 which is a painted pattern, the other light shading elements 302, 303, 304, 305, and 306 are made of papers with the opaque artwork areas 31 and the penetrating openings 32.

Referring to FIGS. 5A and 5B of the drawings of this preferred embodiment of the present invention, each of the plurality of control spacers 20 comprises a spacer frame 21 having a frame opening 22, and a couple arrangement 23 for detachably connecting to the adjacent spacer frame 21 or the light platform 10. As shown in the drawings, each coupling arrangement 23 comprises one or more first coupling elements 231 at a first side of the spacer frame 21 and one or more second coupling elements 232 at an opposite second side of the spacer frame 21. Accordingly, the adjacent control spacers can be detachably connected with each other via the detachable connection between one or more first coupling elements 231 of one control spacer 20 and the corresponding one or more second coupling elements 232 of the other control spacer 20. In other words, a control spacer 20 can be detachably connected to an adjacent control spacer 20 by detachably coupling the first coupling elements 231 of the control spacer 20 with the second coupling elements 232 of the adjacent control spacer 20.

As shown in FIGS. 5A and 5B of the drawings, an illustrated control spacer 20 of this preferred embodiment in the drawings comprises four first coupling elements 231 at four corners at a top side of the spacer frame 21 and four second coupling elements 232 at four corners at a bottom side of the spacer frame 21. Accordingly, the illustrated control spacer 20 can be connected to an adjacent control spacer 20 at a top side thereof by the connection between the four first coupling elements 231 of the illustrated control spacer 20 and four second coupling elements 232 of the adjacent control spacer 20 at the top side, and also can be connected to an adjacent control spacer 20 at a bottom side thereof by the connection between the four second coupling elements 232 of the illustrated control spacer 20 and four first coupling elements 232 of the adjacent control spacer 20 at the bottom side.

As an example, each of the first coupling elements 231 can be a connecting pin while the corresponding second coupling element 232 is a hole. According to this preferred embodiment, each of the first coupling elements 231 can be magnetically coupled with the corresponding second coupling element 232. The corresponding first and second coupling elements 231 and 232 are magnetically coupling elements having different magnetic poles. Each of the spacer frame 21 may be formed by a plastic material while each of the first and second coupling elements 231 and 232 can be integrally embedded into the spacer frame 21 through an integral embedding process.

Alternatively, each of the first and second coupling elements 231 and 232 can be adhered to the spacer frame 21 via a glue. Preferably, each of the spacer frame 21 may have a groove for receiving each of the first and second coupling elements 231 and 232 so that an exposed surface of each of the first and second coupling elements 231 and 232 is in a same plane with a surface of the spacer frame 21, so that when two adjacent spacer frames 21 are stacked with each other, there is no gap is formed between two adjacent spacer frames 21 for preventing light beams from the light source 11 to leak out.

According to this preferred embodiment, four magnets 230, which are respectively embedded into the four corners of the corresponding spacer frame 21, can be employed to form four first coupling elements 231 and four second coupling elements 232. Each of the four magnets 230 have different magnetic poles at two opposite sides thereof. Accordingly, a first end portion of each of the magnets 230 functions as a first coupling element 231 while an opposite second end portion of each of the magnets 230 functions as a second coupling element 232.

The plurality of spacer frames 21 is preferred to be shaped and sized to overlap with each other to form a spacer stack on the light platform 10 for spacing the plurality of light shading elements 30. A light shading element 30 can be placed between two spacer frames 21 and the light shading element 30 is arranged at a position that it will not cover the coupling elements 231 and 232, so that the function of the coupling elements 231 and 232 will not be influenced.

As shown in FIG. 4 of the drawings, the support base 12 of the light platform 10 further comprises one or more connecting members 125 at a support surface 1221 for detachably coupling with the second coupling elements 232 of a bottom control spacer 20 via a suitable coupling manner. Similarly, each connecting member 125 may be embodied as a magnetically attracting member to be magnetically coupled with the second coupling elements 232 of the bottom control spacer 20 for detachably coupling the light platform 10 with the plurality of control spacers 20.
